CostInBillingCurrency in CSV Does Not Match Portal Cost After Azure Credits Applied - Cost Management

We exported our Azure Cost Management data for a single month (April'26) for a subscription to a CSV file. When we sum the CostInBillingCurrency column in the CSV, we get a number that very much higher than that of cost on Azure Portal page. (20 times higher)

We noticed that 100% of rows in the CSV have IsAzureCreditEligible = true, and the CSV has no rows showing credit deductions.

Our specific questions are:

  1. Why does the CSV not include credit deduction rows, and is this expected behavior?
  2. Is there a way to export cost data that shows the post-credit cost per row, so we can allocate the actual $ back to individual teams and resources?
  3. Is there a specific export type or API (e.g., ActualCost vs AmortizedCost) that would give us the post-credit breakdown at row level?

    Hi Shriya,

    Yes, this can be expected. IsAzureCreditEligible = true only means the charge is eligible to be covered by Azure credits; it does not mean the value in CostInBillingCurrency has already had those credits deducted. Credits are applied at the billing/account level, so they generally do not appear as negative credit rows against individual resources in Cost Management usage exports.

    Neither ActualCost nor AmortizedCost provides a true “post-credit cost per resource” field. AmortizedCost mainly changes how reservation and savings-plan purchases are distributed over their benefit period; it does not allocate Azure credits across usage rows.

    If you need to charge the actual amount paid back to individual teams, you would need to reconcile the usage costs with the billing-level credit adjustment and define your own allocation method for distributing those credits across eligible resources/teams.

    Thank you, and feel free to respond back for more assistance.
